Have your face scanned in just a few millionths of a second.

The latest version of the iPhone is expected to launch in September and will feature updated tech that improves the device's speed and efficiency. But there will also be a significant security update, according to a report from the Korean Herald.

The new phone will come equipped with a facial recognition scanner with 3-D sensors that can scan a user's face in only a few millionths of a second. These same 3-D sensors will also help support potential augmented reality applications.

Previously, Apple relied on a different form of biometric security—the fingerprint scanner. The scanner took about one second to sense a fingerprint and provide access.

The facial recognition tech will also expected to be used for Apple Pay authorization, according to the report.
